We stayed at River Bend RV Resort
in Harrisburg, OR recently for a Guaranty Travelers rally. Outstanding meeting facilities. They have a restaurant on site w/dining room overlooking the river, and ~30 motel rooms & pool. About 5 minutes from Guaranty's shop in Junction City, and 20 from the variety of services in Eugene/Coburg. Sites are flat & level, coach parks on a concrete slab, tho some of the patio sides are immediately on lawn so if it rains you are in mud, and some are extended slab. That mud issue may improve as the landscape matures, but for our site the manager hauled out a large piece of astro-turf cuz the grass was not really in and it looked like rain.
Great service oriented attitude (what can we do to make you happy?), and a pretty place. Excellent for a rally or group. Close to services. Easy in & out, and sites angled for easy parking. Mostly back-in sites, 12 pull thru.
Rally rate was about $32 out the door per nite in August 09.
We didn't take advantage of the restaurant as it wasn't open when the rally booked, so rally was catered. If booking a rally, you can get a quote for catering from them, and if camping and you don't want to cook- they will deliver to your site (I asked but we didn't take advantage after 3 days of catering).
